Congratulations on re-homing this needy grey. What will you be naming your new companion? I would have your grey's former owner help you to learn what you should do but you should be the one to interact with your grey. Sit with him, talk to him and leave the cage door open so he knows he is welcome to come out to see you if he chooses. As for his cage, new, old does it really matter, you are giving this sweet grey a new beginning on life. I re-homed an Eclectus a couple of months ago. New name, new cage and a new life. He doesn't seem to miss any of those old things and he has stopped plucking and shrieking. Karma to you Valerie for your loving and kind heart!
